Freezing Your Eggs, Sperm or Embryos for IVF

No Comments

When eggs, sperm, or embryos need to be stored, they will be frozen at the private fertility clinic in London. Freezing can preserve the cells or embryos so that they can potentially be thawed and used for IVF in the future. There is no limit to how long the eggs, sperm or embryos can be stored, but there is a chance that some or all of the stored material will be damaged by the freezing and thawing processes, so it may not be viable.

Storing Eggs

It is possible to freeze your own eggs for use in the future, usually due to fertility concerns or a medical condition. If you are already undergoing fertility treatment, it is very rare for the eggs to require storage. Sometimes donor eggs will need to be frozen for transport to the private fertility clinic in London or until you are ready to use them. However, if a large number of eggs are collected from you or your donor, it is more common for them all to be fertilised to increase the chances of getting a viable embryo.

Storing Sperm

Sperm can also be frozen for future use. This will usually only be necessary if your fertility is declining or for medical reasons. Sperm may also be frozen if you are using a sperm donor who isn’t able to provide a fresh sample. If you are having fertility treatment, you will usually be asked to provide a fresh sample when the eggs are ready to be fertilised.

Storing Embryos

In vitro fertilisation can produce more embryos than can be implanted in a single cycle. If you have additional embryos, it is possible to store them at the private fertility clinic in London. You may want to do this in case they are needed for future cycles of IVF, in case you decide to have more children in the future or simply because you want to preserve the embryos.
